Going from normal mode to hard mode

I have been trying to reboot while having a girlfriend to cure my pied. In the beginning there were great signs of light and I was able to have successful sex and maintain an erection. After a few weeks of orgasms with my girlfriend I feel like I have been stuck in the flatline. I have gone 77 days without watching porn and now that I am leaving for college again I am hoping to do a successful hard mode reboot. Were the 77 days of normal mode even a help for my reboot like a step in the right direction? Can the rest of my reboot in hard mode help me out of the flatline?????? I have been pmo'ing for 5 years and wonder how long it will take to get my erections back.... I'm 20 years old. Thank you for the help!!!!!
